A ball thrown in the air vertically from ground level with initial velocity 37 m/s has height h(t) = 37t − 4.9t2 m at time t (in

Nesterboy [21]

Answer:

46.57

Step-by-step explanation:

Given that:

h(t) = 37t - 4.9t²

When the ball reaches the ground, then the height is zero;

So, we equate h(t) to zero and solve for t

37t - 4.9t² = 0

t = 0, 7.55

Let the Initial time be a = t = 0

The time the ball reaches the ground be b = 7.55

So, the average height can now be calculated as:

Average height = $\frac{1}{b-a}\int\limits^b_a {h(t)} \, dt$

= $\frac{1}{7.55-0}\int\limits^{7.55}_0 (37t-4.9^2) dt$

= $\frac{1}{7.55-0}\ (\frac{37(7.55)^2}{2} - \frac {4.9(7.55)^3}{3})$

= $\frac{1}{7.55-0}\ (351.6104208)$

= 46.57091665

≅ 46.57 to (2 decimal places)

1) Which linear equation BEST represents the line of best fit for the scatterplot? A) y = x B) y = 3x C) y = -3x D) y = 5x + 1 2

Tresset [83]

Answer:

1) A. y = x + 2

Once a line of best fit has been placed upon a scatter graph it is straightforward to find the equation. The general equation of a straight line is: y = mx + c Where m is the slope (gradient) of the line and c is the y-intercept.

4) d. strong positive correlation.

The slope of the line is positive. Most points lie close to the line.
